These Threadmill 1200 thread count Supima cotton sheets in queen size deliver a sateen-sheened, hotel-quality sleep surface with deep pockets and breathable natural fibers.

Elevate your bedding with a luxuriously soft sheet set woven from extra-long staple Supima cotton and finished in a smooth sateen. The Threadmill 1200 collection combines a high thread count hand with durable construction, generous sizing, and responsible manufacturing practices to give you a polished look and reliable performance night after night.

How do these sheets feel and perform night after night?

The sateen weave creates a silky, slightly lustrous face while the Supima fibers add strength and softness that improves with washing. You’ll notice a smooth surface with less pilling and a cozy drape that stays comfortable in multiple seasons.

• 1200 thread count for a dense, soft hand without excess weight
• 100% Supima long-staple cotton for durability and softer fibers over time
• Sateen finish for a smooth, subtly shiny appearance

Will the fitted sheet stay secure on a deep mattress?

The fitted sheet is cut with a deep 17" pocket and an all-around elastic hem to fit thicker mattresses and toppers. This design reduces shifting and bunching so the bed looks neat and stays comfortable through the night.

• Fitted sheet dimensions: 60" W x 80" L with 17" deep pocket
• All-around elastic keeps corners snug and prevents slipping
• Large flat sheet and two pillowcases complete the four-piece queen set

How should I care for these sheets to preserve their look?

Machine wash in cool or warm water, then remove and fold promptly to minimize wrinkles and shrinkage. The Supima fibers and careful finishing resist fading and pilling when laundered according to the instructions.

• Machine wash at room-temperature settings; avoid high-heat drying
• Fold or remove from dryer promptly to reduce creasing
• Finished to resist loose fibers, fading, and excess pilling
